how about using

• line-bot-sdk-nodejs/lib/webhook/model/followEvent.ts

  Lines 24 to 35 in 4da15ba

  	export type FollowEvent = EventBase & {
  	type: "follow";
  	/**
  	* Reply token used to send reply message to this event
  	*/
  	replyToken: string /**/;
  	/**
  	*/
  	follow: FollowDetail /**/;
  	};
  	export namespace FollowEvent {}

• line-bot-sdk-nodejs/lib/webhook/model/followDetail.ts

  Lines 13 to 18 in 4da15ba

  	export type FollowDetail = {
  	/**
  	* Whether a user has added your LINE Official Account as a friend or unblocked.
  	*/
  	isUnblocked: boolean /**/;
  	};

?

Yeah, it's usable but the type defined in the lib/types still not up to date. Mostly people reference the type definition from this file, so should we update it as well ?

I mean we usually import the type like this

import { FollowEvent } from '@line/bot-sdk';

which is not up to date yet.

rather than

import { FollowEvent } from '@line/bot-sdk/dist/webhook/api';

Sorry for late review.
The way to deprecate in the code is incorrect,(

line-bot-sdk-nodejs/lib/types.ts

Lines 1 to 3 in 8b67d81

	/**
	* @deprecated Use types generated by openapi spec instead.
	*/

) but as announced here, the current code (lib/types.ts) is no longer maintained and will be removed soon.

• https://github.com/line/line-bot-sdk-nodejs/releases/tag/v8.0.0

It is recommended to use the new code.

Can you migrate to the new code? On the other hand, if you need this immediately, we can merge this and release by increasing the patch version. (though we don't maintain old code)

Got it. I think I'll update my dep to use the newer version. Thanks. So this PR will be closed.
